--- Comment #51 from Allan <allan4229@gmail.com> ---
Tried to install the RX480 on the other PC : the card is too big that it
touches the RAM slot's tabs. Can't install it.

In time, seems like the errors delay a little bit when setting
randomize_va_space=0. Was testing it for the CPU and noticed that amdgpu
delayed to fail, but it still failed.

What happened :
- the screen got granulated with pinkish colors as usual
 - desktop extended this behavior
- but I could operate the system
- tty was black and white (normal)
- I could restart x server
- colors got normal after restarting
- tried the same application again
- crashed and froze the system

Main difference : 
- now sometimes I can kill the tasks/restart xserver

I registered the times of each event, here follows:

(Firefox was opened in background while I tried to play Left for Dead 2 through
steam)

1. Recoverable delay with granulated colors (l4d2 begins 11:48, occurs 11:50
after some delay while loading the game menu)

kern.log = dmesg

2. Unrecoverable crash (l4d2 begins 12:00, goes well until 12:55 when crashes
everything)
dmesg:
> [Thu Nov 22 12:55:04 2018] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=1688198, emitted seq=1688200

kern.log = dmesg

Xorg log is not reporting anything useful.

I wish I had this luck.
